Create a word problem that matches this system of equations:
x+y=15
4x+10y=120

see the explanation

Step-by-step explanation:

The word problem could be

The sum of the ages of John and Mary is equal to 15 years.

If we multiply John's age by four and add 10 times Maria's age, the total number of years is 120.

Find the age of John and Mary

Let

x ---> John's age

y ---> Mary's age

we know that

----> equation A

----> equation B

Solve the system of equations by graphing

Remember that

The solution of the system of equations is the intersection point both graphs

using a graphing tool

The solution is the point (5,10)

see the attached figure

therefore

John's age is 5 and Mary's age is 10

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
